dev-null-undefinedandClaude f47fb86077 LR-BEHAV-GPU: say once when no GPU is found, instead of quietly rendering on the CPU ...

With GPU rendering on and no graphics adapter at all (wgpu: "no GPU adapter among …", e.g. no
Vulkan loader: a `cargo run` outside `nix develop` on NixOS), every render ran on the CPU, much
slower, and only Settings ▸ Performance, Help ▸ System Info and `perf.gpuReason` said why.

The desktop app now queues one start-up notice per session once the device has been tried
(`gpu::ready()`, never blocking): "No graphics processor found: LightCraft renders on the CPU, which
is much slower. Details in Help → System Info.", on Linux with "On NixOS, start it from `nix
develop`." (→, not ▸: no installed font paints ▸.) `panels::notices::gpu_notice` decides from the
reason: nothing when the GPU was turned off (preference, LIGHTCRAFT_GPU, LIGHTCRAFT_GPU_BACKEND=off),
only a software adapter was skipped, or it failed later. Headless sessions and tests never show it
(`app.gpu_notice` is set by the desktop app only). Translated in all nine catalogs; one README
sentence in the Nix section.
